This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizability—for the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples.
We investigate how congressional stock purchases may impact investor expectations of firm outcomes. Specifically, we argue that because there is information asymmetry regarding how public policy may impact a firm and investors perceive that members of the U.S. Congress possess insider governmental information and power over the regulatory landscape of a firm, a legislator's purchase of firm stock will generate abnormal returns. Furthermore, we argue that this response will be greater if the Congressperson has jurisdiction over the firm through committee assignments, and that the effect of jurisdiction will be strongest when the firm ties itself directly to the politician through political strategies (e.g., lobbying sponsored legislation, committee testimony, and political action committee contributions). We find support for many of our arguments in a broad sample of senator stock purchases between 2012 and 2020. Managerial summary: We examine stock purchases of the members of the U.S. Senate for years 2012-2020 and find that stock purchases by senate members generate abnormal returns. We also find that abnormal
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
